Loading
In order to be able to choose the right type and dimension of grating it is important to know the loading that the grating will be subjected to. Below and on the following pages are extracts from load tables and descriptions of some simple rules.
Stainless steel grating is manufactured in the same way as other press welded gratings but of stainless steel material 303, 316 Grades. The grating is supplied un-treated or etched according to requirements.
Aluminium grating is manufactured in full size panels 6000 x 1000 mm. It can be supplied either in this size or cut to panel size requirements. This grating can also be supplied with edging strips. The grating is available in 2 standard mesh opening sizes from stock. Other sizes are available on longer delivery. Safety grating is available with serrated finish on the top side of the load bar. The grating is manufactured of Aluminium alloy Al Mg Si.
When establishing layout drawings the panel size should be based on the standard width of the grating (1000 mm) to achieve best possible economy. If the grating is to be laid across a number of support beams, choose a length of grating that spans across as many supports as possible.
This results in less deflection under load, you get a pleasant overall pattern and a minor number of joints. If you on the same occasion order gratings with the same length of load bearing bars, you can make the cross bar match.
SURFACE TREATMENT
Epoxy Varnish Is coated on the galvanized grating giving it excellent protection against corrosion. Thickness of layer 150 - 200 µm.
Primer
Grating can be treated with zinc chromate primer or shop primer
Bitumen (Asphalt treatment)
This finish is used mainly indoors. It can be carried out on self-colour or galvanized grating.
Treatment of stainless steel
Stainless steel grating can be shot blasted, pickled or electrolytically treated to produce a good surface finish
